Just read an interesting piece on how Ronald Reagan won the 'cold war' and defeated Russia principally by empowering Russia's neighbours and imposing the harshest of sanctions on Russia itself, causing Russia to eventually crumble.
Interesting read also from the point of view that Reagan who was reputed to be a war monger, later became known as a peacemaker because of various nuclear reduction treaties.
What I found slightly worrying is that everything Regan did to achieve the fall of Russia, Donald appears to be doing the polar opposite.
